add 1 "Dark Magician", or 1 non-Ritual Monster that mentions it, from your Deck to your hand, then place 1 card from your hand on top of the Deck
Monsters that can fuse are specifically shown on the cards of monsters that can be brought out by fusing (this is called a Fusion Monster Card)
On the left, theres a dense cluster of tiny sets: Secret Lairs (limited-run promotional sets, typically 510 cards), Commander preconstructed decks, and various special releases
They have numbering over 204 for their set, and normal card backs so they can be played in standard decks
Aleister the Invoker of Madness Aleister is a huge support card for Invoked, allowing you to tutor out key spell cards from your deck each time a monster is fusion summoned
Perhaps The Pokmon Company wanted more power out of its star, too
